Working night shifts increase the risk of heart disease and cancer
For many people working the night shift is one of the reasonable thing to do and has become the demands of the job. But not many are aware that the people who work the night shift should pay more attention to their health.
A study conducted by researchers at Harvard Medical School revealed that people who spend at least three days to work night shifts per month has a risk of lung cancer and heart disease is higher as compared with those who did not work the night shift.
These results obtained researchers led by Dr. Eva Schernhammer after observing 75,000 nurses in the United States for 22 years. In addition to increasing the risk of certain diseases, working the night shift also increases the risk of death due to various reasons up to 11 percent, as reported by Web MD (05/01).
The risk of death from heart disease in people who work night shifts for six to 14 years increased to 19 percent higher and 23 percent higher in people who are already working the night shift more than 15 years. Meanwhile, participants who work the night shift more than 15 years to 25 percent higher risk of developing cancer of the lungs.
The results of this study have been published in the American Journal of Preventive Medicine. Even so researchers still need to do more research to determine the factors other than working the night shift that could affect their risk of heart disease and cancer.
